25x18mm Dyed Blue and Cream Dragon Vein Crackle Agate Cabachone Stone S2200B
You are buying the stone in the picture. Dyed blue... shades to entirely cream on some stones. Stone is called dragon vein crackle agate. Each one varies quite a bit so I am listing individually. Check sizes carefully, this is 25x18mm different size stones look similar in pictures and I often sell same stone in a number of sizes.
